Due to the configuration, the number of divisions is limited to three or four, and there is a problem that the amount of reduction in eddy current loss in the conductor is small. Furthermore, if the number of divisions is increased and a dislocation wire that does not require concentrated dislocation is used, the ratio of the conductor occupying the cross section of the conductor (occupation ratio) decreases, and in order to obtain required performance, the conductor 10 must be cut off. There was a problem that the area had to be increased.
